Waveguide to microstrip transition

24 Feb 2018 The performance of such a transition provides a high return loss (>20 dB) over the entire Q-band. The transition between the microstrip and the WR22 waveguide has to accomplish two different requirements: impedance matching and a modal conversion between the two devices. The microstrip antenna is usually connected to the millimeter-wave circuit through a waveguide. Thus a microstrip line to waveguide transition is required to 11 May 2016 Abstract—A broadband microstrip line-to-waveguide (MSL-to-WG) transition is developed for E-band applications. In order to achieve a PDF | The paper describes a novel Ka Band waveguide to microstrip line transition. The compact design has the attractive features of Low insertion loss, good In this work, we proposed a waveguide-to-microstrip transition based on E-plane probe. It is designed for ultra-wideband D-band (110 GHz - 170 GHz) millimeter-wave applications. In order to save space, this design arranges the input and output ports in a perpendicular way. It is easy to fabricate with simple structure. In this paper, a novel transition, based on the ridged-waveguide together with the microstrip-probe approach, is proposed. With this structure, it overcomes theA probe at one end of the microstrip line is inserted into the perpendicular waveguide whose one end is short-circuited by the back-short waveguide. The configuration is shown in Figure 3. A dielectric substrate with conductor patterns on its both sides is placed on an open-ended waveguide (WR-12 standard waveguide). Design and test data are presented for waveguide-to-microstrip probe transitions that cover millimeter-wave frequencies from 26 to 110 GHz. The broadband d.
